OpenTopography Bulk Download

This resource provides bulk downloads of raster data from datasets hosted by OpenTopography. It is designed for advanced users seeking to download large amounts of data quickly and who have the bandwidth, expertise, and software necessary to manage the gigabytes of data available. We expect that users accessing bulk data have the ability to automate downloads from the command line via tools such as wget, curl, or a download manager such as DownThemAll

Each dataset directory contains all of the raster data for a given data collection and are typically organized into various layers type for download efficiency. When possible, a README file in the directory describes the dataset organization and other important information. Metadata for all datasets can be accessed via the OpenTopography Metadata page and users should consult the collection survey report for additional information on data organization, file naming conventions, coordinate systems, etc.

By accessing data via OpenTopography you agree to acknowledge OpenTopography and the dataset source as specified in the dataset metadata and on OpenTopography's data acknowledgement page in publications, presentations, and other materials produced using these data.

Eel River Critical Zone Observatory July 2014 Lidar Survey (Angelo)

This dataset was collected by NCALM for PI Dr. William Dietrich, University of California, Berkeley. The Eel River CZO is a multi-disciplinary research collaborative based at the University of California, Berkeley. CZO research explores how biotic and abiotic factors interact in the near-surface environment (from bedrook to tree tops) and how these relationships impact environmental processes.

The requested survey area consisted of a polygon located 145 km West of Chico, CA. The polygon encloses approximately 57.1 square km. This survey was performed with an Optech Gemini Airborne Laser Terrain Mapper (ALTM) serial number 06SEN195 mounted in a twin-engine Piper PA-31-350 Navajo Chieftain (Tail Number N931SA).

(*) The SRTM service requires each side of the bounding box be greater than approximately 250 meters. The SRTM service is now disabled for this job. To enable it again, please try a larger bounding box.

These options allow users to describe and keep track of their jobs. Information entered below is recorded along with other job parameters in your personal lidar Job archive accessed via myOpenTopo (available only to registered OpenTopography users).
